Thanks for reply sunshine,

It works with me finally. It needs special sequence at operating.

1- Download and run preloader using Eclipes of DS-5, and stop execution at main() by breakpoint .

2- Download .sof file to fpga using quartus programmer.

Then enjoy working FPGA-to-HPS SDRAM Bridge in Bare-metal.
